Aspects
A hypercube knows n! 2n Aspectial variants, which are obtained by coordinate reflection ( --> ) and coordinate permutations ( --> i]) effectively giving the Aspectial variant:
nHm~R perm(0..n-1); R = k=0∑n-1 ((reflect(k)) ? 2k : 0) ; perm(0..n-1) a permutation of 0..n-1Where reflect(k) true iff coordinate k is being reflected, only then 2k is added to R. As is easy to see, only n coordinates can be reflected explaining 2n, the n! permutation of n coordinates explains the other factor to the total amount of "Aspectial variants"!
Aspectial variants are generally seen as being equal. Thus any hypercube can be represented shown in "normal position" by:
= min (by reflection) < ; k = 0..n-2 (by coordinate permutation)(explicitly stated here: the minimum of all corner points. The axial neighbour sequentially based on axial number)

Famous quotes containing the word aspects:
“The North American system only wants to consider the positive aspects of reality. Men and women are subjected from childhood to an inexorable process of adaptation; certain principles, contained in brief formulas are endlessly repeated by the press, the radio, the churches, and the schools, and by those kindly, sinister beings, the North American mothers and wives. A person imprisoned by these schemes is like a plant in a flowerpot too small for it: he cannot grow or mature.”
—Octavio Paz (b. 1914)
“... of all the aspects of social misery nothing is so heartbreaking as unemployment ...”
—Jane Addams (1860–1935)
“It is always a sign of an unproductive time when it concerns itself with petty and technical aspects [in philology], and likewise it is a sign of an unproductive person to pursue such trifles.”
—Johann Wolfgang Von Goethe (1749–1832)
