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