Dear Forum, This is perhaps not strictly a GAP question, but anyway....
I've been working on some computations in GAP (using the GRAPE and other packages), testing certain properties of distance-regular and strongly regular graphs. (I can go into more detail if necessary--but the SetOrbit package of Pech and Reichard has been especially useful.) There is an online catalogue of strongly regular graphs on Ted Spence's webpage: http://www.maths.gla.ac.uk/~es/srgraphs.php The graphs are given by their adjacency matrices; however, as given these matrices are not immediately readable by GAP. Does anyone know of an easy way to convert them into the right format (i.e. adding the commas and brackets)? For cases where there are a small number of graphs, I've been able to do search/replace in a text editor to add the commas, then add the brackets manually---but this isn't really feasible when there are 32,548 matrices of size 36x36.
