I often have to generate random Lucas numbers so I created this simple online utility that does it for me. It lets you generate however many random Lucas numbers you need from the given range. It works in the browser and is powered by alien technology from the future.

How Does This Random Lucas Number Generator Work?
end (start and end of the random Lucas numbers range) are valid and generates an array
ls for short) that contains all Lucas numbers in this range. To pick a random Lucas number from
ls array, it generates a random index
i by using the formula
floor(rand() * ls.length) and selects the
i-th number by calling
ls[i]. It then uses the
push() function to add this number to the
randomLucas array that contains all randomly selected Lucas numbers. To prevent the repetition of Lucas numbers, it removes the just selected
ls[i] from the
ls array by using the
splice(i, 1) function. It repeats this picking process until
randomLucas array has as many numbers as you've specified in the
count option (length of the random Lucas sequence), or until the
ls array becomes empty. Finally, it combines all the elements of the
randomLucas array into a string and puts the
separator value between them.
