Presentation

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

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

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

GAP

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

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