Presentation

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

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

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

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

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