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

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