Presentation

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

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

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

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

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