Presentation

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

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

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