Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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

GAP

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

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