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