 | {n} | The n is a non-negative integer. Matches exactly n times. For example, “o{2}” does not match the “o” in “Bob” but does match the two “o”s in “food”. |
 | {n,} | The n is a non-negative integer. Matches at least n times. For example, “o{2,}” does not match the “o” in “Bob” and does match all the “o”s in “foooood”. The sequence “o{1,}” is equivalent to “o+”. The sequence “o{0,}” is equivalent to “o*”. |
-| {n,m} | The m and n are non-negative integers, where “n <= m”. Matches at least n and at most m times. For example, “o{1,3}” matches the first three “o”s in “fooooood”. “o{0,1}” is equivalent to “o?”. Note that you cannot put a space between the comma and the numbers. |
+| {n,m} | The m and n are non-negative integers, where “n ≤ m”. Matches at least n and at most m times. For example, “o{1,3}” matches the first three “o”s in “fooooood”. “o{0,1}” is equivalent to “o?”. Note that you cannot put a space between the comma and the numbers. |
 | ? | When this character immediately follows any of the other quantifiers (*, +, ?, {n}, {n,}, {n,m}), the matching pattern is non-greedy. A non-greedy pattern matches as little of the searched string as possible, whereas the default greedy pattern matches as much of the searched string as possible. For example, in the string “oooo”, “o+?” matches a single “o”, whereas “o+” matches all “o”s. |
 | . | Matches any single character except “\n”. To match any character including the “\n”, use a pattern such as “[\s\S]”. |

 | \W | Matches any non-word character. Equivalent to “''[^A-Za-z0-9_]''”. |
