Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

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

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