Presentation

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

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

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