Please create a complete list of all “keyboard-adjacent 3-letter combinations,” i.e. keystroke sequences that can be typed with each letter adjacent on an alphanumeric, US-style computer keyboard (keys are also considered “adjacent” to themselves, allowing for repeat combinations such as “eed”, in other words, the key “e” is considered adjacent to itself, and to the letters w,r,d, and s). Non-alphabetic letters and punctuations are not allowed. Only lowercase letters are to be included.
For further clarification: considered adjacent are: ft, ji, aw, but not, for instance, gr.
Examples of combinations to include are: dcv, rfv,vfr,vfg,xds, tgg, qaa, qaq, qqq – since all these can be typed “adjacently” on a US-style computer keyboard. Examples for sequences not to include are qza, qsa, cvr.
Deliver as text document, with letter combinations delimited by line returns.
