Presentation

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

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

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