Presentation

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

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

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