The Metropolitan Police said there were several incidents of violent disorder across the capital, including around Whitehall, on November 11.
Detectives are investigating a range of offences including inciting racial hatred, racially aggravated public order offences and assault on police officers.
Scotland Yard on Tuesday released images of 20 men from the counter protest they are seeking to identify.
Commander Kyle Gordon said: “Public order policing doesn’t end when the event is over, and since remembrance weekend our teams have been working around the clock to identify those involved in any criminality that took place on the day.
“They’ve trawled through hundreds of hours of CCTV footage and are continuing to review evidence to help with enquiries.
“We need the public’s help to track down these men, who we want to speak to in connection with a range of offences.
“As with any public order event, we know that people may have travelled from outside of London, so we’re asking for people across the country to take a look at those pictured and get in touch if they recognise anyone.”
There was a counter demonstration to a huge pro-Palestine rally with up to 300,000 people calling for a ceasefire in Gaza. Police were drafted into the capital from across England to deal with the protests. Exclusion zones were thrown up around the cenotaph and US and Israeli embassies to head off trouble.
The force said it made 145 arrests on the day for offences for possession of weapons, criminal damage, public order, inciting racial hatred and possession of drugs.
