Getting magic numbers 134217734 etc in a repetable keymap

[Ramesh Nedunchezian <rameshnedunchezian@outlook.com>]

I would like to create a repeatable keymap which has magic number
134217734 etc in it using either `define-key' or any other API.

I have tried the following, and it desn't work

    (define-key sexp--repeat-map
      (vector
       (car
	(listify-key-sequence
	 (kbd "C-M-f"))))
      'forward-sexp)

Getting numbers like 134217734 etc in to the repeatable keymap are
important for successful setting up of repetition. That is, for
repetition to succeed, the condition below in `repeat-post-hook' need
to succeed.

    (or (memq last-command-event keys)
	(memq this-original-command '(universal-argument
				      universal-argument-more
				      digit-argument
				      negative-argument)))

... and when I invoke C-M-f `last-command-event' comes out as 134217734.

----------------

For now I have hard-coded `sexp--repeat-map' as below, and this works
as expected.  But I want a cleaner and less-hackish recipe for achieving the same.



(setq sexp--repeat-map
      '(keymap
	;; How can I get 134217734 here?
	
	;; (define-key sexp--repeat-map (kbd "C-M-f") 'forward-sexp)
	;; puts a nested list in keymap

	;; The numerical vaues here are values of `last-command-event'  in
	;; `repeat-post-hook'
	(134217734 . forward-sexp)
	(134217730 . backward-sexp)
	(134217729 . beginning-of-defun)
	(134217733 . end-of-defun)
	(134217732 . down-list)
	(134217749 . backward-up-list)

	;; I can get 102 here with
	;;   (define-key sexp--repeat-map "f" 'forward-sexp)
	(102 . forward-sexp)
	(98 . backward-sexp)
	(97 . beginning-of-defun)
	(101 . end-of-defun)
	(100 . down-list)
	(117 . backward-up-list)))

(progn
  (put 'forward-sexp 'repeat-map 'sexp--repeat-map)
  (put 'backward-sexp 'repeat-map 'sexp--repeat-map)
  (put 'beginning-of-defun 'repeat-map 'sexp--repeat-map)
  (put 'end-of-defun 'repeat-map 'sexp--repeat-map)
  (put 'down-list 'repeat-map 'sexp--repeat-map)
  (put 'backward-up-list 'repeat-map 'sexp--repeat-map))

----------------

FWIW, to convert C-M-f to 102, I used this

    (vector
     (event-basic-type
      (car
       (listify-key-sequence
	(kbd "C-M-f")))))
