COMMENTS
The sequence is an analog of the Yellowstone sequence A098550 with a more stringent condition on neighboriong terms at distance 2. However, we conjecture that, as with A098550, this is a permutation of the positive integers.
By definition, every pair of neighboring terms at distance 2 are strictly connected numbers as defined in comment in A257112.
