I would like to state the following:
"Another simple class/type/kind of A is the one of B"
One possibility would be to write
"B constitutes/represents another simple class/type of A",
but this doesn't stress enough that we are dealing with another class of A and hence doesn't fit the context. This is why I would like to start the sentence with "Another simple class of A", but I am missing a good word for is, because I don't think that it is the correct word.
"Another simple class of spanning graphs is the one of Hamilton cycles."
I do not like the repeated appearance of "of" here.
Thank you very much for your help.
