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