  2. Palindromic number - Wikipedia

    en.wikipedia.org/wiki/Palindromic_number

    The only known non-palindromic number whose cube is a palindrome is 2201, and it is a conjecture the fourth root of all the palindrome fourth powers are a palindrome with 100000...000001 (10 n + 1). Gustavus Simmons conjectured there are no palindromes of form n k for k > 4 (and n > 1).

  3. Palindromic sequence - Wikipedia

    en.wikipedia.org/wiki/Palindromic_sequence

    Palindrome of DNA structure A: Palindrome, B: Loop, C: Stem A palindromic sequence is a nucleic acid sequence in a double-stranded DNA or RNA molecule whereby reading in a certain direction (e.g. 5' to 3') on one strand is identical to the sequence in the same direction (e.g. 5' to 3') on the complementary strand.

  5. Longest palindromic substring - Wikipedia

    en.wikipedia.org/wiki/Longest_palindromic_substring

    The loop at the center of the function only works for palindromes where the length is an odd number. The function works for even-length palindromes by modifying the input string. The character '|' is inserted between every character in the inputs string, and at both ends. So the input "book" becomes "|b|o|o|k|". The even-length palindrome "oo ...

  6. Inverted repeat - Wikipedia

    en.wikipedia.org/wiki/Inverted_repeat

    Four different sets of inverted repeats are involved in this structure. Sets 1 and 2 are the stem of stem-loop A and are part of the loop for stem-loop B. Similarly, sets 3 and 4 are the stem for stem-loop B and are part of the loop for stem-loop A. Pseudoknots play a number of different roles in biology.

    A palindrome is a word, number, phrase, or other sequence of symbols that reads the same backwards as forwards, such as the sentence: "A man, a plan, a canal – Panama". ". Following is a list of palindromic phrases of two or more words in the English language, found in multiple independent collections of palindromic phra

  8. List of palindromic places - Wikipedia

    en.wikipedia.org/wiki/List_of_palindromic_places

    A palindromic place is a city or town whose name can be read the same forwards or backwards. An example of this would be Navan in Ireland. Some of the entries on this list are only palindromic if the next administrative division they are a part of is also included in the name, such as Adaven, Nevada.

  9. Palindromic prime - Wikipedia

    en.wikipedia.org/wiki/Palindromic_prime

    Any number that can be expressed as a repetition of just one digit d in some base must trivially be palindromic in that base and must be a multiple of d in every base. Accordingly, no number that consists only of a string of repetitions of the same digit in at least one base, can be a prime unless it is a string of 1s in that base.
