DV, or routing 101...

just when you thought you were becoming proficient at routing, advanced concepts and the like, area id's and autonomous systems, ad infinitum, you suffer a setback with the likes of this:

a router has two primary functions:
path determination and packet forwarding

time to live (ttl) has a maximum value of 255, and has nothing to do with hop count
hop count refers to the number of routers a packet must pass through en route from source to destination

which of the above (path determination, packet forwarding) is hop count concerned with?

hop count determines distance and is placed in the routing table (path determination) while ttl determines how long a packet will be allowed to traverse the network before being discarded (packet forwarding)

easy, right?
