Presentation

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

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

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