Presentation

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

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

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