Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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