Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 28 points:

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