Problem Statement

Let X be the group generated by uu and vv, such that

X=\langle u, v \mid u^{46} = 1, v^{40,488,236} = 1, vu = uv^{27,636,633} \rangle $$. What is the order of the group X?

Reasoning Process

[THOUGHT] The group X is defined by the presentation X=u,vu46=1,v40488236=1,vu=uv27636333X = \langle u, v \mid u^{46} = 1, v^{40488236} = 1, vu = uv^{27636333} \rangle. This presentation defines a semidirect product of the cyclic group u\langle u \rangle of order 46 and the cyclic group v\langle v \rangle of order 40488236. The relation vu=uv27636333vu = uv^{27636333} can be rewritten as vuv1=u27636333vuv^{-1} = u^{27636333}, which defines an automorphism of u\langle u \rangle given by multiplication by k27636333mod46k \equiv 27636333 \mod 46. Computing 27636333mod4627636333 \mod 46 yields 39, so the automorphism is multiplication by 39 modulo 46. The multiplicative order of 39 modulo 46 is 11, as 39111(mod46)39^{11} \equiv 1 \pmod{46}. Since the automorphism has finite order and the relations are satisfied, the group is finite. The order of the semidirect product is the product of the orders of the two cyclic groups, which is 46×4048823646 \times 40488236. Calculating this product gives 46×40488236=186245885646 \times 40488236 = 1862458856.

1862458856\boxed{1862458856}

Reasoning Process

[THOUGHT] We need to compute the order of the group X. First, compute k = 27636333 mod 46. Then check if k^40488236 ≡ 1 mod 46. If yes, the order is 46 * 40488236; else, 1. [/THOUGHT] [PYTHON] k = 27636333 % 46 m = 40488236 if pow(k, m, 46) == 1: order = 46 * m else: order = 1 print(order) [/PYTHON]
