The symbol that represents both greater than and less than is "<>". However, it's important to note that this is not a commonly used symbol for expressing the concept of being simultaneously greater than and less than. The more widely recognized symbols for these concepts are ">" for greater than and "<" for less than. When comparing two values, ">" is used to indicate that the value on the left is greater than the value on the right, and "<" is used to indicate that the value on the left is less than the value on the right. So, in most cases, you would not see or use the symbol "<>".
