Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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