Presentation

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

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

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