Presentation

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

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

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

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

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