Presentation

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

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

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

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

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