Presentation

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

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

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