Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 28 points:

(6,9)(10,12)(13,14)(15,19)(16,17)(18,20)(21,22)(23,26)(24,25)(27,28);(7,11)(10,12)(22,25)(26,28);(6,9)(10,12)(14,17)(15,20)(22,25)(23,27);(5,6)(7,10)(8,9)(11,12)(13,15)(14,18)(16,20)(17,19)(21,23)(22,26)(24,27)(25,28);(5,7)(6,10)(8,11)(9,12)(13,14)(15,19)(16,17)(18,20)(21,22)(23,28)(24,25)(26,27);(3,4);(1,2)(3,4)

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

gap> G := Group((6,9)(10,12)(13,14)(15,19)(16,17)(18,20)(21,22)(23,26)(24,25)(27,28), (7,11)(10,12)(22,25)(26,28), (6,9)(10,12)(14,17)(15,20)(22,25)(23,27), (5,6)(7,10)(8,9)(11,12)(13,15)(14,18)(16,20)(17,19)(21,23)(22,26)(24,27)(25,28), (5,7)(6,10)(8,11)(9,12)(13,14)(15,19)(16,17)(18,20)(21,22)(23,28)(24,25)(26,27), (3,4), (1,2)(3,4));
