Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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