Open Problems Column

Abstract

This Issue's Column! This issue's Open Problem Column is by William Gasarch and is A Problem on Linked Sequences Inspired by an Oliver Roeder Column Request for Columns! I invite any reader who has knowledge of some area to contact me and arrange to write a column about open problems in that area. That area can be (1) broad or narrow or anywhere inbetween, and (2) really important or really unimportant or anywhere inbetween.
