Dick,

You want the answer for lossless or real components?  For lossless 
components starting at the generator a shunt capacitor of 831.93pF and 
then a series inductor of 269.96nH to the load will match to 25.67 + 
j18.68.  There are many more circuits that will achieve the same match.

This calculation can be done in just a few seconds with a free program 
like SimSmith.  I have a YouTube channel using SimSmith to solve all 
kinds of ham radio and RF topics if you are interested.

Is this what you want?
