Presentation

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

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

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

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

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