Presentation

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

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

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