Presentation

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

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

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

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

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