Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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

GAP

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

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