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

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