Not a full answer, but maybe it will help you get closer:

Assuming these are let frequencies:

• the distribution is quite flat. It's surprising (to me) that a text with only 102 letters contain all letters except q and w. The Scrabble letter distribution suggests that j, y, c, x and z are quite uncommon I'm swedish words

• the letter w is not part of the list

• do the letters d, e, l, n, t, z mean anything to you? It doesn't match any swedish dictionary words

Could it be two lists with "tags"? Both lists are multiple of both 2 and 3, so maybe a list with:

Fe
Ca
Xl
...

Possibly with numbers behind (fa 8342). Then you might have used this to figure out which elements were missing in one list.
