Default factoring 2ⁿ-2 equivalent to factoring 2ⁿ-1(I think)

2n1= a*b

factoring 2n-2 equivalent to factoring 2n-1

if this condition is met (a-1) divided by (b-1)
then 2n-1 =1 mod b-1


example
M11 = 0 mod 23 and 88 =0 mod 22
211-2 = 0 mod 22



M23 = 0 mod 47
223-2 = 0 mod 46





M73 = 0 mod 439
273-2 = 0 mod 438

M83 = 0 mod 167
283-2 = 0 mod 166

M131 = 0 mod 263
2131-2 = 0 mod 262
