Presentation

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

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

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