Welcome.
Yes, it is a tv-play scenario, it was published in Poland among other stories in the book ,,Przekladaniec"; and the story about Tarantoga's meeting with geniuses is, if I'm not wrong, titled "Wyprawa Profesora Tarantogi" (,,Professor Tarantoga's Expedition") but it still wasn't translated into engish, of what I know...
That Tarantoga story was probably once published in Poland as addition to early edition of Star Diaries, but it's still in Polish, and that's about it.
I'm afraid it wasn't translated to other languages at all (I hope I'm wrong, though).
Cheers
