Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

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

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

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

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