Presentation

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

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

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

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

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