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