Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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