Presentation

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

A minimal faithful permutation representation — 6 generators on 26 points:

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

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

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