In geometry, a 9-cube is a nine-dimensional hypercube with 512 vertices, 2304 edges, 4608 square faces, 5376 cubic cells, 4032 tesseract 4-faces, 2016 5-cube 5-faces, 672 6-cube 6-faces, 144 7-cube 7-faces, and 18 8-cube 8-faces.
It can be named by its Schläfli symbol {4,37}, being composed of three 8-cubes around each 7-face. It is also called an enneract, a portmanteau of tesseract (the 4-cube) and enne for nine (dimensions) in Greek. It can also be called a regular octadeca-9-tope or octadecayotton, as a nine-dimensional polytope constructed with 18 regular facets.
It is a part of an infinite family of polytopes, called hypercubes. The dual of a 9-cube can be called a 9-orthoplex, and is a part of the infinite family of cross-polytopes.
Cartesian coordinates for the vertices of a 9-cube centered at the origin and edge length 2 are
while the interior of the same consists of all points (x0, x1, x2, x3, x4, x5, x6, x7, x8) with −1 < xi < 1.
Angel Poem
I’ve seen an angel
She crawled out her grave
Then just stared at me
Without a word to say
Then that same angel
Just took my broken hand
Placed it on her face
Her expression was sad
Forgiven angel
Gazing stares into her eyes
Let go of my hand
Then spoke with her mind
“Oh thou broken boy
Do the world a favor
Take the blood dagger
And just fucking kill me”
She was my angel
She was my hater
She was my lover
She was my reaper
