Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 22 points:

(1,2)(3,4)(5,6)(7,8)(9,10)(11,12,14,13)(15,16,20,22)(17,19,18,21);(3,5,6,4)(7,9,10,8)(12,13)(15,17,20,18)(16,21,22,19);(4,5)(7,9,10,8)(15,17,20,18)(16,21,22,19);(3,5,6,4)(7,9,10,8)(16,22)(19,21);(11,13)(12,14)(15,18,20,17)(16,19,22,21);(3,5)(4,6)(7,9)(8,10)(11,13)(12,14)(15,19)(16,18)(17,22)(20,21)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((1,2)(3,4)(5,6)(7,8)(9,10)(11,12,14,13)(15,16,20,22)(17,19,18,21), (3,5,6,4)(7,9,10,8)(12,13)(15,17,20,18)(16,21,22,19), (4,5)(7,9,10,8)(15,17,20,18)(16,21,22,19), (3,5,6,4)(7,9,10,8)(16,22)(19,21), (11,13)(12,14)(15,18,20,17)(16,19,22,21), (3,5)(4,6)(7,9)(8,10)(11,13)(12,14)(15,19)(16,18)(17,22)(20,21));
