There seems to be a bug in the sparse6 string generator. sage: G=graphs.EllinghamHorton78Graph() sage: G.sparse6_string() ':~?@M_GEA_w?C`WGEaOOGaWWI_OmGBGKL`w}OcXINCxQGCPUWCp]WdPeOEh[Zc`q^Fh}_gXwagyAfGaYfhAa^IYEgIyqlji}ojREqfa{rlbCtljKvjbatMYWv_Jq|hBy{hSAdn{M *\\*OCRAeRtEa_wVlSHBhagjkBgzpCY}OSr'
Notice the "\\" in the above string. This should have been "\" instead, i.e. one backslash instead of 2. Normally sparse6 encoded graphs are stored in a "myFile.s6" file. Storing the above String in a file, and then reading it with another piece of software produces incorrect results, due to the additional "\". Note however that in the following command is correct: sage: F=Graph(':~?@M_GEA_w?C`WGEaOOGaWWI_OmGBGKL`w}OcXINCxQGCPUWCp]WdPeOEh[Zc`q^Fh}_gXwagyAfGaYfhAa^IYEgIyqlji}ojREqfa{rlbCtljKvjbatMYWv_Jq|hBy{hSAdn{M *\\*OCRAeRtEa_wVlSHBhagjkBgzpCY}OSr') Here, the extra "\" is indeed required since the graph is constructed from a String.
