"""CPU-only verification test for Cayley Graph Diameters of SL(2, Z/pZ)"""

# SL(2, Z/2Z) has order 6. Generators g_a = [[a,1],[1,0]] mod 2 for a=1..5
# mod 2: a=1,3,5 give [[1,1],[1,0]], a=2,4 give [[0,1],[1,0]]
# So effectively 2 distinct generators. BFS from identity in group of order 6.
# Diameter should be small (2-3).
