I know that the prefix for eight is "oct". Does this mean that the word I am looking for starts with"oct"? I have done quite a bit of research. Almost every time the first website listed is this one. I really hope that this will be the end of my research! Thank you!

    Please give us an example. It’s not clear whether you mean n*8, n^8, or n*(m^8), etc

    A verb 'to octuple' is certainly morphologically well_formed, but I think it is rare, and for good reasons. I think that 'sextuple' is at the limit of widely used multiples. 'Septuple' begins to sound a bit odd, 'octuple' somehow less so, but nine times? Nonuple? Surely not. As for 'ninefold' (by analogy with 'eightfold'), you cannot 'ninefold' something. You might increase it nineford.
