Jacobite rising of 1745

The Jacobite rising of 1745 was the attempt by Charles Edward Stuart to regain the British throne for the exiled House of Stuart. The rising occurred during the War of the Austrian Succession when most of the British Army was on the European continent. Charles Edward Stuart, commonly known as "Bonnie Prince Charlie" or "the Young Pretender", sailed to Scotland and raised the Jacobite standard at Glenfinnan in the Scottish Highlands, where he was supported by a gathering of Highland clansmen. The march south began with an initial victory at Prestonpans near Edinburgh. The Jacobite army, now in bold spirits, marched onwards to Carlisle, over the border in England. When it reached Derby, some British divisions were recalled from the Continent and the Jacobite army retreated north to Inverness where the last battle on Scottish soil took place on a nearby moor at Culloden. The Battle of Culloden ended with the final defeat of the Jacobite cause, and with Charles Edward Stuart fleeing with a price on his head, before finally sailing to France.

In mathematics

Forty-five is a triangular number, and in particular the sum of all the decimal digits (0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45). It is the smallest triangle number (after 1) which can be written as the sum of two squares. It is also a hexagonal and 16-gonal number,

45 is the sixth positive integer with a prime factorization of the form p²q, with p and q being prime.

33 is the aliquot sum of 45 and the aliquot sequence of 45 is (45, 33, 15, 9, 4, 3, 1, 0).

Since the greatest prime factor of 45² + 1 = 2026 is 1013, which is much more than 45 twice, 45 is a Størmer number.

In base 10, it is a Kaprekar number and a Harshad number.
