Talk:Pentomino

For making diagrams see m:Template talk:Square 8x8.--Patrick 11:41, 5 Jun 2005 (UTC)

Inappropriate medium

There is a subdivision into two subsets of six pentominos which each have a 6×5 solution. This provides eight 6×10 solutions, and also eight solutions of 5×12.

"I know something that you don't, nananananana!" Instead of mentioning the existence of these solutions in text, without giving any hint as to what they are, it would be so much better to show a picture! I'll put it on my to-do list.

O well, Patrick seems to consider this 'his' article and is prepared to start a revert war, so I won't waste my time here.

It is not at all my article, I only reverted some odd deletions.--Patrick 22:28, 11 September 2005 (UTC)

(With the solution shown, the other one is obtained by rotating a set of seven pentominoes, or put differently, by rotating the four leftmost and the rightmost to the other side.)

We are not trying to list the solutions exhaustively here. If you insist on including this, show a picture instead of describing a picture in text.

…but including rotation and reflection of a subset of pentominoes (sometimes this is possible and provides in a simple way an additional solution; e.g., with the 3×20 solution shown, the other one is obtained by rotating a set of seven pentominoes, or put differently, by rotating the four leftmost and the rightmost to the other side).

A picture is worth more than a thousand words here.

3D

I added 3 demention part. I am sure the solutions I posted are not in good format. However, I cannot find good way to show 3d object on screen. Can anybody help? AIEA 16:53, 1 December 2005 (UTC)

Incorrect Fact

"Other patterns that 9 of the 12 Pentomino pieces will solve, are the shapes of each of the 12 pieces enlarged x3. The German Wikipedia article mentions this too, giving examples in images."

This is wrong. All 12 shapes can be remade at a 3x3 scale. The hardest to achieve is X, but it is not impossible. —The preceding unsigned comment was added by 202.89.154.135 (talk) 08:55, 11 April 2007 (UTC).

Inspiration for Tetris?

There should be a source on this - I've come up empty. — Preceding unsigned comment added by 62.198.148.168 (talk) 04:52, 25 June 2018 (UTC)

List of Games (Board and Video Games)

The primary function of this article is about Pentominoes as geometrical shapes. When adding cultural reference (like games), they should predominately feature pentominoes. Many thousands of games have pentominoes as a small subset of randomly falling blocks. I have removed the games that seemed to only mention pentominoes as one of many types of shapes, and to keep the games that are clearly about pentominoes. — Preceding unsigned comment added by 204.134.214.98 (talk) 21:04, 3 October 2020 (UTC)

30 pentacubes?

My back of the napkin math (plus some searching), seem to indicate the existence of 30 pentacubes, not just 29.

Since my calculations also indicate every cube can individually fit in a 5x3x2 space, theoretically the following could be possible.

6x5x5 10x5x3 15x5x2 25x3x2

Triplication

An interesting exercise is to make a three times version of one pentomino from nine of the others. This may be done for all twelve pentomonos 87.115.149.91 (talk) 10:42, 7 October 2022 (UTC)

Inappropriate phrasing

Tetris shouldnt be used as an example, even if it is specified that is uses tetrominoes MouseDahBidoof (talk) 09:30, 19 June 2024 (UTC)
