Presentation

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

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

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

GAP

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