Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

(1,2)(8,10)(11,12,15,13)(14,16,18,17);(4,6)(8,10)(11,12,15,13)(14,16,18,17)(20,23)(24,25);(3,4)(5,6)(7,8,9,10)(14,18)(16,17)(19,20)(21,24)(22,23)(25,26);(3,4)(5,6)(7,8)(9,10)(11,12,15,13)(14,17,18,16)(19,21,22,26)(20,24,23,25);(3,4)(5,6)(7,8)(9,10)(11,13,15,12)(14,16,18,17)(19,20)(21,24)(22,23)(25,26);(11,14)(12,16)(13,17)(15,18)(19,21)(20,25)(22,26)(23,24)

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

gap> G := Group((1,2)(8,10)(11,12,15,13)(14,16,18,17), (4,6)(8,10)(11,12,15,13)(14,16,18,17)(20,23)(24,25), (3,4)(5,6)(7,8,9,10)(14,18)(16,17)(19,20)(21,24)(22,23)(25,26), (3,4)(5,6)(7,8)(9,10)(11,12,15,13)(14,17,18,16)(19,21,22,26)(20,24,23,25), (3,4)(5,6)(7,8)(9,10)(11,13,15,12)(14,16,18,17)(19,20)(21,24)(22,23)(25,26), (11,14)(12,16)(13,17)(15,18)(19,21)(20,25)(22,26)(23,24));
