Presentation

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

A minimal faithful permutation representation — 8 generators on 28 points:

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

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

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