Streszczenie
We consider the question of whether the trigonometric system can be equivalent to some rearrangement of the Walsh system in $L_p$ for some $p\not =2$. We show that this question is closely related to a combinatorial problem. This enables us to prove non-equivalence for a number of rearrangements. Previously this was known for the Walsh–Paley order only.
