Is finding cache size possible with information given?
An n-way set associative cache can store n different entries for a given index in the cache array.  So the 8-way acts like an 8x multiplier as compared with a direct mapped cache (1-way set associative).  

So, I would take it that the line size of 24 with 26 lines per set and 23-way set associative is 213 or 8k bytes.  

A next question might be how big are the tags that are stored in the associations?   22 (from the address space) - 4 (for cache line size) - 6 (the number of entries in the array), means that a tag size of 12 bits is needed.
