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