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