Presentation

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

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

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