jcreedcmu / d20 puzzle from reddit

	#!/usr/bin/perl

	# http://www.reddit.com/r/math/comments/1j86p4/d20_perfect_layout/
	# asks whether there is a 20-sided die such that for every face f, the value
	# on face f and the values of all three faces adjacent to f add up to 42.
	# (42 is what you might reasonably hope for, since the average value of a face
	# taking values 1, 2, ..., 19, 20 is 10.5, and we're adding 4 faces)
	# This script prints out an octave expression for M^{-1} v where M is the adjacency
	# matrix of the faces of an icosahedron, and v is a column vector of 20 copies of 42.
