Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

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

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