Comment:
`SRG_279_150_85_75` is an example of a general construction, obtaining a
`2-graph\*`-srg from a `2-graph`-srg. I'll try to add this in
`strongly_regular_graph` DB.
Further on a followup ticket I'd like to have Taylor 2-graphs for
`U_3(q)`, and the corresponding `2-graph\*`-srg (note that in this case
there is no `2-graph` srg, as far as I understand). They should come from
yet to be written more general function, that will also produce `U_d(q)`.
