Presentation

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

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

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