Presentation

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

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

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