Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
